IMPROVEMENT IN" PUMPS.

Specification forming part of Letters Patent No. 133,278, dated November19, 1872.

To all whom it may concern:

Be it known that I, JAMES WILLIAM WHIT- AKER, of Kenosha, in the countyof Kenosha and State of Wisconsin,l1ave invented certain Improvements inPumps, of which the following is a specification, reference being hadto,

the accompanying drawing.

My invention relates to a novel arrangement of operating devicesapplicable to small pumps of all kinds; and it consists in thecombination of a vibrating lever, for the operator to stand upon,withtwo stationary handles to be grasped by him.

Figure 1 is a top-plan view of a double-cylinder pump having my devicesapplied, and Fig. 2 is a perspective view of the same in use.

In the drawing, A represents an ordinary double-cylinder pump, betweenthe cylinders of which I mount astandard, a, supporting a tipping orvibrating lever, B, to the opposite ends of which the two plunger orpiston rods 0 are connected, as shown. On each end of the lever I securea foot-plate, b, so that the operator can stand with one foot on eachplate, and, by throwing his weight first on one foot and then on theother, depress the ends of the lever alternately. To the ends of thepump I attach two rods, E, which extend upward and have their upper endsprovided with handles at such height that they can be readily grasped bythe operator while standing on the lever. As the operator throws hisweighton either end of the lever he, at the same time, pulls strongly onthe corresponding rod, so as to pull himself downward, and thus applythe muscular force of his arm in addition to his weight toward forcingthe end of the lever down. hen operating in this manner his legs arekept straight, or nearly so, and his arms bent at each stroke; but, whenhis arms become fatigued, he may hold them stiff and operate the leverby bending his legs. By thus changing the mode of operation from time totime, so as to throw the work upon the arms and legs alternately, theoperator is relieved from fatigue and enabled to work the pump for along time.

The rods E I make detachable, so that they may be removed when the pumpis not in use in order to prevent them from being bent and to admit ofthe pump being stowed in a small space.

By means of the foot-lever and handles the operator is enabled to applyhis weight and muscular force to great advantage, so as to work a muchlarger pump than otherwise, and to continue the operation for a greatlength of time.

While the devices are especially adapted for application to the form ofpump shown, because the plungers can be connected directly to thefoot-lever, theymay be applied to pumps of all forms and styles bymaking a suitable connection between the foot-lever and the propermoving parts of the pump. In such cases the foot-lever will be aseparate independent part from the pump proper and not a constituentpart, as in the present case.

The footlever and handles may be mounted on a frame or stand bythemselves, and put into the market as an article of tradeso as to beapplied to pumps already in use.

It is obvious that the handles may be dispensed with and the treadlealone used, in

which case a bar or support of some kind should be provided for theoperator to take hold of in order to balance and steady himself.

Having thus described my invention, what I claim is- In combination witha pump provided with a vibrating foot-lever, B, the handles E, arrangedsubstantially as described.
